GUN SIGHTS AND Tl-IE COMBINATION THEREOF WITH A SLEEVE Filed May 21, 1954 INVENTOR. GEoRaE. A. MADMNEK United Sttes Patent GUN SIGHTS AND THE COMBINATION THEREOF;

My invention relates to gun sights and more particularly to a gun sight for single barrel shot guns that may be easily applied to and removed from the barrel of the gun.

In rib sights which have heretofore been applied to; guns, it has been the practice to either form the sight as an integral portion of the gun or to provide extraneous means on the gun to which the rib sight is secured. The addition of extraneous means to guns are of course costly to provide and in such constructions, considerable time is required to fasten the gun sight in place.

It is the aim of the present invention to provide an improved sight for guns of the single barrel type that is inexpensive to construct and which maybe easily and quickly applied to and removed from the barrel of the gun. My improved sight is so designed that when applied to a gun, it may be maintained in a definiteposition to provide a direct true line sight and is either free to move with the barrelof the gun when the metal of the barrel expands during firing or the sight may be so applied that the metal forming the barrel of the gun is free to move relative to the sight when it expands. In the preferred form of the invention, the sight includes a sleeve which protects the barrel of the gun from being scratched, nicked, or the like, and also protects the hunter frompossible injury in the eventof an accidental blow out of the barrel'during firing, By use of the improved sight of the present invention, alight coat of oil or grease may be applied to the barrel of the gun to protect the metal of the barrel from oxidation and the sleeve associated with the rib sight preventsthe oil from being displaced during handling of the gun. In accordance with the present invention, a rear sight may also be provided which if. desired may be formed integral with or welded or otherwise setuned to the rib sight or it may be formed separately from the rib sight and inserted in place when desired. It is therefore an object of the present invention to provide an improved rib sight for single barrel shotguns which may be easily applied to and removed from the barrel of the gun and which when applied to the barrel of the gun will'provide a true line from the stock of the gun to the bead-sigh Another object of the invention is to I provide an improved rib sight for guns including a rear sightrwhich may be formed integral with or permanently secured in any desired manner to the rib sight or which may be formed as a separate piece and which may be easily in- 'serted in place when desired.

further object of the invention is to provide an improved rib sight for guns of the single barrel type which isheld against rotative movement and which may be applied to the barrel of the gun in such a manner that it may move with the barrel of the gun during expansion of theibarrel when the gun is fired.

f stillj further ob'ect of the invention is to provide an'impro'ved rib sight for guns in combination with a :slfejeve'which is mounted in cooperative relation with a portion of the jgun to hold the rib sight in place and Patented Oct. 15, 1957 2 which protects the barrel of the gun from accidental damage and also prevents oil or grease applied to the barrel of the gun from being displaced.

My invention will be better understood by reference tothe accompanying drawings in which:

Fig; 6 is a modified form of my improved rib sight showing means integral therewith for attachingit to a single barrel shot gun;

Fig. 7 is a cross sectional view taken on a plane passing through the line 7-7 of Figs. 1 and 3, looking in the direction of the arrows; V

Fig. 8 is a cross sectional view taken on a plane passing through'the line 8-8 of Fig, 1;' and V Figs. 9, 10 and 11 are cross sectional'views, which shows a modified form of the rib sight.

While the gun sight of the present invention may be applied to a single barrel shot gun of any desired type and of'any desired guage, for purposes of illustration, a commercial gun of a well known type is'shown in the drawings having a barrel 1 extending from the stock 2 in which a break off occurs between the 'stock and the barrel and the barrel is provided with a downwardly extending bracket 3 which forms a support for one end of the tube 4 on which the pump 5 slides.

According to oneform of my invention, an improved each of 'sight is provided which includes a rib 6 which extends from substantially the stock of the gun to the front end of the barrel and in which means are provided to maintain the rib sight in a true line position. As illustrated in Fig. 1 of the drawings, the rib sight is provided with a sleeve 7 which surrounds the barrel and means are provided to maintain the sleeve firmly in place. For this purpose, the sleeve is provided with a notch 8, the 'op{ posite edges of which engage the opposite sides of the bracket 3. To provide additional means for holding the rib sight in place, theheaded screw "91 which forms the bead sight of the gun may be removed from the'gun and inserted through a threaded opening in the rib 6, the shank of. which is threaded in the usual opening :at the free end of the barrel, or if desired, the threaded shank of the screw, the head of which forms the bead sight of the gun in my-improved sight may be threaded through an opening at a point in proximity to the free end of the usual bead sight with-its threaded end arranged adjacentto the threaded screw 10 forming the bead "sight of the gun, 'as illustrated more particularly in Fig. 3 of the drawing. t a

It will of course be understood that during firing, the barrel of the gun is heated to a temperature which is higher than the temperature of the sleeve. If the screw 9, the head of which forms the bead sight of the .gun is threaded into the barrel of the gun, whenthe barrel of the gun expands, the beadjsightv and the end of the sleeve are free to move forward with the e'xpansion'of the metal forming the barrel of the gun and will of 9 course return to their original positions when the barrel of the gun cools. When the shank of screw 9 is arranged rearwardly of the screw 10, the barrel of the gun is free to expand to a greater degree than the sleeve without in any manner affecting the position of the rib sight. 7 Y I For certain purposes, such as forfshooting deerand particularly when slugs are utilized, it is desirable to provide a rear sight 11 in addition to the bead sight. The rear sight may be of any desirable shape. For instance, it may be substantially circular or tubular in shape or it may be substantially angular in shape and provided with a V-shaped groove as shown in the drawings. .-The rear sight may be formed integral with the rib sight or it may be provided with a V-shaped arm 12 welded or otherwise secured thereto as shown in Figs. 1 and 4, or the rear sight and the V-shaped arm may be formed separately from the rib sight and the arm 'of the'rear sight may be inserted in the V-shaped' groove of the rib sight as shown in Figs. 3 and 5.

As previously stated, the rear sight 11 is used principally to provide a rifle-aiming effect when utilized for special hunting, such as when hunting for deer, and may of course be omitted when the gun is utilized for other purposes as shown in Fig. 2. In the construction shown in Fig. 2, one end of the rib sight engages the stock of the gun and the rib sight provides a true line from the stock of the gun to the bead sight. 7 The rib sight may be of any suitable form that provides a true-line from the stock 'of the barrel to the bead sight. It may, for instance, be V-shaped as shown in Figs. 1 to 8, or it may be of any other suitable shape. For instance, the sleeve may terminate in a substantially rectangular-shaped rib as shown in Fig. 9, or the sides of the sleeve may first converge upwardly at an angle and terminate in a substantially flat surface as shown in Fig. 10, or the sleeve may be provided with upwardly extending sides which terminate in an inclined V-shaped groove as shown in Fig. 11. When utilizing one of the rib sights as shown in Figs. 9 to 11, it will of course be understood that the arm on the rear sight, when used, will conform to the shape of the groove and may be welded to the rib sight or may be shaped to fit within the groove or grooves formed by the rib sight.

The rib and sleeve portion of the present invention may be formed of any desirable material, such as metal, fiber glass, or plastic, and may be painted any desired color. For instance, the rib and sleeve may be painted blue for general use to blend with the metal of which the barrel is formed. Because the rib and sleeve assembly may be constructed at low cost, each hunter may be provided with several of the assemblies, each of which may be utilized for a different purpose. For instance, when hunting ducks or geese, the assembly may be painted brown to blend with marsh grass. The assembly when thus painted does not have as much light reflectivity as the metal of the barrel of the gun and therefore does not serve as a warning to the ducks or geese that a hunter may be present. For deer hunting, the assembly may be painted red to provide protection for the hunter in woods or forests. When formed of plastic material, the rear sight may be molded integral with the rib sight or a separate piece may be molded in the form of the rear sight and a projecting arm as shown in Fig. 5.

Another modification of my invention is shown in Fig. 6 of the drawings. This modification is similar to that shown in Figs. 1 to with the exception that the sleeve does not'extend the full length of the barrel but consists of two spaced portions 7a and 7b, the rear portion 70 having a notch therein to receive the bracket 3 on the gun to prevent relative movement of the bead sight and the front portion in combination with the rear portion being effective in maintaining the rib sight in place. Y
